Dellums' spokeswoman Karen Stevenson said the move would take place in phases beginning in the next several weeks. The 15 officers had been providing extra security at the airport in the wake of the Sept. 11 terrorist attacks. The Alameda County sheriff's department has agreed to take over those duties.

Eight officers and two sergeants will move into problem-solving officer slots funded by Measure Y, a 2004 ballot measure that paid for extra officers and anti-violence programs, on or around July 1, Stevenson said.

The remaining five officers -- part of the airport's bomb-sniffing canine unit -- will stay at the airport until deputies are trained to take over those responsibilities.
